The invention relates generally to receptacle closures and more specifically to a closure adapted to conveniently dispense the contents of tooth powder receptacles or the like.

The main object of the invention resides in the provision of a receptacle having an opening in the wall of the cover member thereof, whereby powder contents from the said receptacle are dispensable by the use of the same hand that grasps the said receptacle.

A further object of the invention resides in the provision of a receptacle of the above type wherein the cover member is provided with a simple and durable mechanism adapted to successively deposit a small quantity of the powder contents on a brush, such as a tooth brush, during the revolution of a rotary element mounted on the cover member of the said receptacle.

An incidental object of the invention resides in the provision of means for uniformly distributing powder on a tooth brush without loss or waste of powder during the depositing operation. In addition the invention affords other features, such as the simplicity and durability of construction, the serviceability and efficiency in use and low cost of manufacture.

These objects and other incidental ends and advantages of the invention will hereinafter appear in the progress of the disclosure and as pointed out in the appended claims.

Accompanying this specification are drawings showing three preferred embodiments of the invention and wherein corresponding reference numerals designate corresponding parts throughout the several views.

Figure 5 is a plan view of the second preferred form of the invention being partly in section and partly broken away.

Figure 6 is a sectional view of the second preferred form of the invention along the vertical plane of the axis showing the upper portion of the cover and receptacle.

Figure 7 is a fragmentary and sectional view of the left side of Figure 6 showing another construction of a baffle plate.

Figure 8 is a plan view of the inside of the inner surface of the cover member of a receptacle which is circular in cross section.

Figure 9 is a diametrical sectional view of the upper portion of a receptacle which is circular in cross section and wherein the upper wall of 5 a cover member is provided with an opening for the dispensing of powder contents.

In accordance with the invention and in accordance with the accompanying drawings, numeral Ii] designates the continuous vertical wall 10 of a container such as a tooth powder container, while numeral ll represents the bottom wall of the said container having a beaded periphery. In Figures 3 and 5, the receptacle is shown as being elliptical in cross section, while in Figure 8 the receptacle is shown as being circular in cross section. It is distinctly understood, however, that any other geometrical shape of a receptacle in cross section may be resorted to wherever desirable. The wall H] at one side of the receptacle is provided with a cut-away shoulder portion ID, the said shoulder portion 1 ll serving to allow free passage of powder contained in the receptacle through an orifice provided in the cover member of the said receptacle, the said cover member being designated by numeral l3. Below the upper limit of wall ID of the receptacle and slightly below the lower limit of shoulder I0 is a bead l2 designed to serve as a limiting stop for the lower edge of the vertical wall of the cover member I3. The cover member I3 is provided with a top wall l5 and an orifice l4 along the vertical wall of the cover member and being intermediate the height thereof. As shown in Figure 1, orifice I4 is preferably located in the vertical plane of the longitudinal axis of the said cover member.

The top wall I5 of cover member I3 is provided with a rotary conveyor whereby powder from receptacle I0 is conveyed to and out of orifice M situated in the cover member.

The aforementioned rotary conveyor is mounted in the top wall of cover member l3 and comprises an upper disc l! and a lower rotary conveyor l8. The upper disc I! has a lipped and a preferably roughened outer edge H, the said edge projecting above the outer face of top wall E5 of the cover member and slightly beyond the rounded edge of the vertical wall of the cover member adjacent orifice E4. The rotary conveyor l8 comprises a circular vertical wall and a top wall 18, the said circular wall having a series of radially and inwardly disposed recesses I9. Upper disc I! and rotary conveyor I8 are keyed together above and below the top wall 15 of the cover member of the receptacle, by means of a series of radially disposed spurs 23 adjacent the center of top wall l8. The said spurs 23 result from notched out portions in the top wall l8 of the rotary conveyor and penetrate an orifice l6 in the top wall 15 of the cover member. Spurs 20 penetrate a series of radially disposed and aligned orifices in the center of upper disc 5?, the said spurs being inwardly bent along the upper surface of disc 'I 1, whereby the rotary conveyor I8 is made to rotate with the rotation of upper disc H.

The first preferred form of the invention shown in Figures 1, 2, 3 and 4 is provided with a rotary conveyor is whose Vertical wall is substantially tangent to the inner face of the ver-- tical wall l3 of the cover member at orifice I4.

At the same time the rotary conveyor I8 is confined within the vertical wall of the cover member of the receptacle. By inverting the receptacle containing powder such as tooth powder recesses iii are filled therewith and by maintaining the receptacle in this position the contents of recesses l9 fall upon the'bristles of a tooth brush when rotating disc ill with the fingers of the same hand that grasps the receptacle.

' Thus a dispenser is provided which. eliminates waste and which is controllable with the same hand holding the tooth powder receptacle. 7

The second preferred form of invention is shown'in Figures 5 to 8 inclusive. The second preferred form of the invention shows a receptaclehaving a continuous vertical wall Mia, a

shoulder portion'at one end thereof Ill, a bead l2 situated sligh ly below the lower limit of shoulder it, a cover member [3 and an orifice I4 in the vertical wall of the cover member sub- 7 stantially intermediate the height thereof. As

7 shown in Figures 5 and 6 the vertical wall l3 of the cover member is provided with a baffle plate l3" whereby the contents from the receptacle are prevented from flowing into the cover member and out of the orifice l4 when the receptacle is inverted for dispensing. The said baffle plate 13" as shown in Figure 6 projects inwardly from the inner surface of the vertical wall [3' of the cover member while in Figure 7 a corresponding baffle plate I 2 is shown as being an integral and inward projection of the vertical wall 10a of the receptacle. I5 is the top wall of the cover member and is providedwith an orifice l6 at the center of upper disc 11" and rotary conveyor 18'. The said orifice H5 in top wall I5 is plugged by means of a central depression of the disc H", the said disc 11 being provided with a lipped and roughened periphery H. The rotary conveyor I8 is provided with a series of teeth I9'constituting the vertical wall thereof. Spurs 23i projecting upwardly from the top wall IB of the conveyor penetrate the orifice l5 and the inner radially disposed orifices in the disc IT". The

said spurs are inwardly bent along the upper face of the said disc l1" therebyrserving as the keying means between disc I1" and rotary conveyor 18''.

Figure 8 shows a similar construction as presented in Figures 5, 6 and 7, except that the receptacle and cover member are circular in cross section, numeral 2| designating the vertical wall of the cover member and numeral 22 designating the orifice therein. 7

Figure 9, showing the third preferred form of 7 the invention wherein the opening in the cover member is provided in the upper wall thereof, shows the vertical wall. of the container designated by numeral 23, the top wall of the vertical container designated by numeral 24 and orifice 75 25 situated in the top wall 24 proximate to the outer edge thereof. The upper wall 24 of the receptacle is provided with a circular orifice 26. Upper wall 24 of the receptacle is provided with a rotary conveyor whereby powder from receptacle 7 23 is conveyed to and out of orifice '25, the said rotary conveyor being comprised of an upper disc 32 and a lower rotary conveyor 21. The upper disc 32 has a lipped and preferably roughened edge 34, the said edge projecting above the upper surface of disc 32. The rotary conveyor as desig- 10 nated by numeral 21 comprises a circular vertical Wall and a top wall, said top wall also being designated by numeral 21, the said circular wall having a series of radially and inwardly disposed recesses 29'. Upper disc 32 and lower conveyor 21 15 are keyed together above and below the upper wall 24 of the receptacle by means of a series of radially disposed spurs 30 adjacent the central orifice 2B of the upper wall 24. The said spurs 39 result from notched out portions in the upper 20 or top wall of the rotary conveyor, penetrating orifice 26 in the upper wall 24 of the receptacle. Spurs 3U penetrate a series of radially disposed and aligned orifices in the center of upper disc.

32, the said spurs being inwardly bent along the 25 7 upper surface of disc 32, whereby the rotary conveyor 2? is made to rotate with the rotation of upper disc 32.

'The upper disc 32 is provided with a series of radially disposed orifices 33 which said orifices 01 register with orifice 25 of the upper wall 24 of the receptacle during rotation of the said disc. 1 Upper disc 32 is'provided with a' funnel member 35 which serves as a spout from which the powder contents issuing from the receptacle through the 35 registration of any one of orifices 33 with orifice 25' are deposited on the brush. The said spout 35 is mounted in the usual manner to upper disc 32, but as shown is brazed to the inner wall of lip 34. The vertical wall 23 is provided with a baiile plate 3| whereby the contents from the receptacle are prevented from flowing into the fun-v nel member 35 when the receptacle is inverted for dispensing purposes. As shown, baffle plate 3| is an integral and inward projection of the ver- 5' tical wall 23 of the receptacle. r
